Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filling molded product manufacturing machine, and more specifically to a non-solid filling material such as water or an elastic filling die having an opening bag-shaped filling portion. The present invention relates to a filling and molding product manufacturing machine for filling food products such as paste-like chocolate, kamaboko, vines, etc., erasers, stationery products such as soap, daily necessities, etc., and then solidifying and molding.

[Prior Art] Conventionally, regardless of whether it is a food product or another food product, a filling mold product has been manufactured using a filling mold.

Such a conventional filling die is formed of a plurality of divided dies which are rigid bodies according to the shape of the filling molding.

The filling mold using such a conventional split mold is one in which a filling material is filled in these split molds, the filling material is solidified in the split molds, and then the split molds are divided to take out. It was

[Problems to be Solved by the Invention] However, a filling molded product manufactured by using such a conventional filling mold inevitably has a dividing line of the dividing mold because it is manufactured by using the dividing mold. It was supposed to reduce the commercial value of the manufactured filled molded products.

Further, in order to manufacture a filling molded product having a particularly complicated shape, a large number of split molds are required, which also complicates the manufacturing process.

Further, since the split mold itself is formed of a rigid body, a large amount of cost is required to manufacture the split mold itself, which greatly affects the manufacturing cost. In particular, in the case of high-mix low-volume production, the split-type cost occupies a large amount of the total cost of the filling-molded product, and in reality, it is almost impossible to produce.

Further, when a conventional rigid divided filling mold is used, in the case of a filling whose volume increases or decreases during solidification, the divided filling mold may be damaged by pressurization or depressurization in the solidification process. .

Therefore, according to the present invention, by using an elastic filling mold having an opening bag-shaped filling portion as a filling mold, it is possible to manufacture a filling molded product without a score line, reduce the manufacturing cost of the filling mold itself, and damage the filling mold. In addition to preventive measures, especially when filling with a filling device, no bubbles are generated regardless of the viscosity of the filling material, and even if it is a filling type with a complicated shape, full filling can be performed in detail. The purpose is to provide a machine.

[Means for Solving Problems] In order to solve the above-mentioned problems, the present invention is
An apparatus for filling a non-solid filling material into an elastic filling die having an opening bag-like filling portion, a solidification device for this filling in the elastic filling die, and a filling solidified from inside the filling portion of the elastic filling die It is characterized in that it is formed with a take-out device for taking out an object, and that the filling device is formed so that the elastic filling mold is positioned in a negative pressure at the start of filling.

[Operation] In the filling molded product manufacturing machine according to the present invention, first, a filling device is used to fill the elastic filling mold with the filling material.

This elastic filling mold uses an elastic material because it is necessary to take out the filled or solidified filling by expanding or contracting the whole in the filling device or the extracting device.

The filling of the filling material into the elastic filling mold is performed by positioning the elastic filling mold in a negative pressure.

Therefore, at the time of filling, there is almost no air inside the opening bag-shaped filling portion, so the air inside the filling material before the start of filling can only be removed in advance, and the filling portion filled It is possible to prevent the inclusion and generation of air bubbles in the product.

Further, the degree of the negative pressure can be made stronger on the side opposite to the opening side than on the inside side of the elastic filling type opening bag-shaped portion, so that the opening bag-shaped filling portion can be inflated. By filling the filling material in the inflated state in this way and gradually reducing the degree of negative pressure after or during filling, the elastic filling type returns to the normal size, so a more precise filling type is used. It is also possible to enable the filling.

After the filling is thus filled inside the elastic filling mold, the filling inside the elastic filling mold is solidified by the solidifying device. Such an apparatus for solidifying the filling includes an apparatus for applying a heat treatment, an apparatus for adding a freezing treatment, and the like, depending on the property of the filling.

Then, the filling material solidified inside the elastic filling mold expands the elastic filling mold so as to be released from the inside of the elastic filling mold, and the extraction device for extracting the filling material inside produces the solidified filling molded product. Is.

However, with regard to this extraction device, the elastic filling mold can be inflated by putting the opposite opening side of the filling portion of the elastic filling mold into a negative pressure state, and as a result, the filled molding product inside can be extracted, and from the opposite opening side. It is also possible to remove the filled molded product by extruding.

EXAMPLES Examples of the present invention will be described below with reference to the illustrated examples.

FIG. 1 is a block diagram showing the overall configuration, FIG. 2 is a partially omitted perspective view, and FIGS. 3 and 4 are schematic diagrams for individually explaining each device.

As shown in the figure, the present invention relates to a filling device 40 for filling the filling material 11 into the elastic filling mold 10 and a solidifying device for solidifying the filling material 11 filled in the elastic filling mold 10 by the filling device 40. 60 and the filling material 11 solidified inside the elastic filling mold 10
And each of these devices 40, 60, 70 are sequentially arranged along the transfer conveyor 20 and are controllably formed by the control device 30. is there.

Further, the transfer conveyor 20 is previously controlled by a pulley 23 which is transmitted by decelerating the rotation of the motor 21 by a speed reducer 22.
It intermittently moves between the devices 40, 60, 70 at a speed set by 30.

Further, on the transfer conveyor 20, a large number of fixed plates 24 are fixed in parallel in the moving direction, and to each fixed plate 24,
A fixing hole 25 larger than the size of the filling molded product 12 as the final molded product is formed.

Here, the elastic filling mold 10 is formed of an opening bag-shaped filling portion 13 and a fixing portion 14 formed near the opening portion of the filling portion 13.

The filling portion 13 is formed in a spherical shape, a columnar shape, or an animal or a specific character as appropriate, and after the filling material 11 filled in the filling portion 13 is solidified, the sphere, the pillar, the animal, or the character. It is designed to have a shape.

Further, the fixing portion 14 is formed as a flange portion having a substantially equal pressure which is continuous with the filling portion 13, is fixed to a large number of fixing plates 24 fixed to the transfer conveyor 20, and the filling material 11 is introduced into the filling portion 13 from the opening. It is formed so that it can be filled freely.

FIG. 3 shows an embodiment of the filling device 40.

Here, the filling device 40 is for filling in a negative pressure atmosphere by a negative pressure mechanism 50 that positions the opening and the counter opening of the elastic filling mold 10 in a negative pressure.

The negative pressure mechanism 50 has an opening facing upward and the first vertically moving mechanism 43 moves the elastic filling mold 10 from above the elastic filling mold 10 to the elastic filling mold 10 in a state where the filling portion 13 hangs downward. Ten
Has an upper cover 51 that moves up and down toward the elastic filling mold 10 and a lower cover 52 that moves up and down toward the elastic filling mold 10 from below the elastic filling mold 10 by the second vertical movement mechanism 44. The lower cover 52 is connected to the pressure source 53, and the lower cover 52 is connected to the lower negative pressure source 54. In the illustrated example, the upper cover 51 is
A filling nozzle 41 communicating with the filling mechanism 42 is fixed, and when the upper cover 51 moves up and down, the filling nozzle 41 also moves up and down at the same time.

Further, the upper cover 51 and the lower cover 52 are elastic filling types, respectively.
It moves up and down to a position where it sandwiches 10 from both sides, and when the elastic filling mold 10 is sandwiched from both sides by both covers, packing (not shown) or the like prevents air from flowing inside and outside the covers 51 and 53. Is formed in.

The upper negative pressure source 53 and the lower negative pressure source 54 are formed of vacuum pumps, valves, pressure gauges and the like, which are not shown.
Further, after the upper cover 51 and the lower cover 52 are brought into close contact with the elastic filling mold 10 from above and below the elastic filling mold 10, by operating the upper negative pressure source 53 and the lower negative pressure source 54, the upper cover 51 and the lower cover 52. The inside of the container is in a negative pressure state, and the inside of the opening bag-shaped filling portion 13 is in a state of almost no air. However, regarding the degree of the negative pressure at this time, it is desirable that the volatile component contained in the filler 11 does not vaporize and foam due to the nature of the filler 11.

Therefore, when the filling material 11 is filled in the filling portion 13 in this state, the filling material 11 can be filled without air being mixed therein. Further, it is not necessary to reduce the size of the filling portion 13 by means such as pressing in order to prevent the air from being mixed.

Further, in the above description, the filling nozzle 41 is fixed to the upper cover 51, and the filling nozzle 41 corresponds to the vertical movement of the upper cover 51. However, the first vertical movement mechanism 43 of the upper cover 51 and the filling nozzle 41. It is also possible to form the above-mentioned nozzle up-and-down moving mechanism as a separate member.

Further, although it has been described that the elastic filling mold 10 is covered with the upper cover 51 and the lower cover 52 and is placed in a negative pressure atmosphere, the both covers 51, 52 may be integrally formed.

Further, although the upper negative pressure source 53 and the lower negative pressure source 54 are described as separate components, they may be connected to the upper cover 51 and the lower cover 52 by sharing the negative pressure source and branching by a branch pipe or the like.

Further, if the degree of negative pressure formed by the upper cover 51 and the lower cover 52 is made stronger in the lower cover 52, the elastic filling mold 10 will swell during filling. Therefore, with the elastic filling mold 10 inflated in this way, a predetermined amount of the filling material 11
The elastic filling mold 10 is made to have a normal size by a means for equalizing the degree of negative pressure after completion of the filling or returning to the atmospheric pressure after the filling is completed. At the time of returning, since the filling 11 reaches the details of the filling portion 13 due to the contraction of the expanded elastic filling mold 10,
The finer elastic filling mold 10 can be filled.

Further, in order to change the degree of the negative pressure of the upper cover 51 and the lower cover 52 in this way, the negative pressure may be separately formed by the upper negative pressure source 53 and the lower negative pressure source 54 as in the embodiment. However, even if the single negative pressure source is used, the negative pressure difference can be appropriately formed by the valve.

Further, when the viscosity of the filling material 11 is high, the filling nozzle 41 of the filling mechanism 42 is located near the opening of the elastic filling die 11 and the filling material is directly fed from the filling nozzle 41 into the filling portion 13 of the elastic filling die 10. When 11 is filled, although air is small due to the negative pressure, it is conceivable that air bubbles may be mixed in and solidified filled molded product 12 may form a cavity.

In such a case, the first vertical movement mechanism 43 for vertically moving the upper cover 51 and the nozzle vertical movement mechanism for vertically moving the filling mechanism 42 including the filling nozzle 41 are separately formed, and both vertical movements are performed. The mechanism may be controlled as follows.

That is, first, the filling nozzle 41 of the filling mechanism 42, the transfer conveyor
With the upper cover 51 penetrating from above 20, it is lowered to the vicinity of the bottom of the filling portion 13 of the elastic filling mold 10 by the first vertical movement mechanism 43, and after slightly filling at that position, the upper cover 51 remains in the same position. Then, only the filling nozzle 41 is gradually operated by operating the nozzle vertical movement mechanism according to the filling amount.

Therefore, at this time, the filling speed by the filling mechanism 42 and the ascending speed by the nozzle up-and-down moving mechanism must have a constant correspondence. In addition, the filling speed and the vertical movement speed must be changed every time the elastic filling mold 10 having a different cross-sectional shape in the height direction is used. Therefore,
If the filling and the vertical movement are performed by a cam or the like, the change of the cam accompanying the change of the elastic filling mold 10 is complicated, so
It is desirable to simultaneously control two variables, the filling amount per unit time and the vertical movement speed, by program control.

In the above description, the filling mechanism 42 is moved up and down by the both vertical movement mechanisms 43 and 44.
And the elastic filling mold 10
May be moved up and down.

Further, when the whole is arranged on the line, the elastic filling mold 10 may be stopped during the filling work by the filling device 40, and an intermittent movement method may be adopted in which the elastic filling mold 10 is moved after the completion of the filling work. It is also possible to form 40 itself so as to be movable along the line, and to fill the filling material 11 from the filling device 40 while moving.

The solidifying device 60 is a device for solidifying the filling 11 inside the elastic filling mold 10.

This device is formed by a heating mechanism, a cooling mechanism, a combination of these mechanisms, or another mechanism.

The specific configuration of the solidifying device 60 is determined by the material of the filling material 11.

For example, when the filling 11 is solidified by cooling, fat, butter, margarine, chocolate, cheese, jelly, ice cream, water, etc., the solidifying device 60 is arranged as a cooling device. Is.

On the contrary, when the filling material 11 is a protein solution, a paste-like kamaboko, a crepe, an eraser or the like which is solidified by heating, the solidifying device 60 is arranged as a heating device.

Furthermore, when the filling 11 is a food product, the filling 11 may have to be solidified and cooked.
In such a case, a cooking device can be attached to the solidifying device 60 for use.

Since the elastic filling mold 10 is used as the filling mold in the present invention, when the filling material 11 is solidified by the solidification device 60, the filling material is
Even if the volume of 11 increases or decreases, the elastic filling mold 10 is not damaged. In the case of the filling type consisting of this rigid body, since the volume increases when water is solidified as the filling material 11, the filling type may burst due to the internal pressure due to the volume increase, but in the present invention, the elastic filling type Since 10 grows as the volume increases, accidents such as rupture do not occur.

FIG. 4 shows a take-out device 70 for taking out the solidified filled molded product 12 from the inside of the filling portion 13 of the elastic filling mold 10.

In the extraction device 70 as described above, when the filling molded product 12 is pushed from the side opposite to the opening of the elastic filling mold 10, the elastic filling mold 10 expands due to elasticity, so that the filling molded product 12 can be pushed out.

Furthermore, after the opening of the filling portion 13 is expanded in advance by an external force, the filling molded product 12 can be pushed out from the side opposite to the opening.

However, in any of the methods, the side opposite to the opening of the filling molded product 12 may be deformed by the pushing force.

Therefore, as a method of not applying an external force to only a part of the filling molded product 12 in this way, there is the following extracting device.
The filling section 13 below is inverted by the pulley 23 to be positioned above, and the filling section 13 is inflated to drop the inside filled molded product 12 onto the take-out conveyor 71 below the extracting device 70. It is a thing. However, regarding the extraction of the filled molded product 12 by such means,
It can also be performed when the filling section 13 is in the horizontal state.

Specifically, a rotary shaft 72 rotated by the motor 21, a negative pressure cam 73 fixed to the rotary shaft 72, a transmission rod 74 swinging by the rotation of the negative pressure cam 73, and a tip of the transmission rod 74. And a negative pressure body 75 pivotally supported on the.

The rotating shaft 72 is a motor for moving the transfer conveyor 20.
The motor 21 that is the same as the motor 21 rotates so as to synchronize with other devices.

The negative pressure cam 73 is formed as a front cam fixed to the rotating shaft 72.

The negative pressure body 75 is connected to the negative pressure source 76 and brings the negative pressure chamber 77 inside the negative pressure body 75 into a negative pressure state.

Although not shown in detail, the negative pressure source 76 is formed of a vacuum pump, a valve, a pressure gauge, and the like.

The negative pressure chamber 77 is formed to have a size that covers the filling portion 13 containing the filling molded product 12, and a cushion 78 is fixed to the upper surface of the inside.

The operation of the extracting device 70 as described above is such that, after the filling material 11 filled in the filling portion 13 is solidified by the solidifying device 60, it is inverted by the pulley 23 to solidify the filling molded product 12 inside. The filling conveyor 13 is intermittently moved by the transfer conveyor 20 so that it is positioned above.

At this time, when the negative pressure chamber 77 covers the upper part of the filling portion 13 and the inside of the negative pressure chamber 77 is brought into a negative pressure state by the negative pressure source 76, the elastic filling mold 10 made of an elastic body causes the negative pressure chamber 77. It will expand so as to come into close contact with the inner wall of the. At this time, not only the filling portion 13 of the elastic filling mold 10 but also the fixing portion 14 are brought into close contact with the inside of the negative pressure chamber 77 as much as possible, so that an opening corresponding to the fixing hole 25 of the fixing plate 24 is formed in the lower portion. It will be.

Then, the filled molded product 12 separates from the elastic filling mold 10,
It will fall downward from the fixing hole 25 of the fixing plate 24 that is larger than the filling molded product 12.

Further, the filled molded product 12 thus dropped downward is placed on the take-out conveyor 71 located at the lower part of the extracting device 70 and transferred to a predetermined position.

When the negative pressure state is formed in this manner, the filling portion 13 extends in the direction in which the elastic filling mold 10 is easily extended, that is, in the illustrated example, the filling portion 13 may collide with the inner upper surface of the negative pressure chamber 77 and the shape may be broken. However, in the illustrated example, the cushion is provided on the upper surface inside the negative pressure chamber 77.
Since the 78 is fixed, you do not have to worry about losing its shape.

Although the negative pressure chamber 77 is formed in a cylindrical shape with a lid in the illustrated example, the negative pressure chamber 77 is shown in the figure in order to prevent the filled molded product 12 separated from the elastic filling mold 10 from being caught in the negative pressure chamber 77. Although it is omitted, it is desirable that the whole is formed to be divergent or that the lower portion is tapered to diverge.

The filling molded product 12 manufactured in this way is an elastic filling mold.
Since the overall shape is determined by the shape of the filling portion 13 of 10,
By making various types of this elastic filling mold 10, a filling molded product 12 of any shape can be made.

Unlike the rigid body, the elastic filling mold 10 can be mass-produced at low cost, so the cost of the filling molded product 12 itself can be low, and unlike the split mold, there is no score line, so the completed filling molding is completed. The product 12 has an extremely natural shape and has high commercial value. Further, since the division into a plurality of directions is unnecessary, the manufacturing process can be simplified.

Further, since the filling into the elastic filling mold 10 is performed by positioning the elastic filling mold 10 in a negative pressure, there is almost no air inside the opening bag-shaped filling portion 13 at the time of filling. Becomes Therefore, it is possible to prevent air bubbles from being mixed and generated in the filling material 11 filled in the filling portion 13 only by removing the air inside the filling material 11 before the start of filling.

Further, by making the degree of the negative pressure stronger on the side opposite to the opening than the inside of the opening bag-shaped portion of the elastic filling mold 10, the opening bag-shaped filling portion 13 can be inflated. In this way, the filling material 11 is filled in the inflated state, and the degree of negative pressure is gradually made the same after or during the filling, so that the elastic filling mold 10 returns to the normal size. It may also be possible to fill the mold.

Further, since the elastic filling mold 10 is used as the filling mold, even if the volume change of the filling material 11 occurs during the solidification process by the solidifying device 60, the elastic filling mold 10 can sufficiently cope with the expansion and contraction of the elastic filling mold 10. There is no damage.

Further, since the extraction device 70 is formed so as to be extracted by using negative pressure, the shape of the filling molded product 12 is not damaged during the extraction process.

In the above description, the elastic filling mold 10 may be made of any material such as soft rubber or soft plastic as long as it can be stretched when pulled.

[Effects of the Invention] As described above, according to the present invention, by using the elastic filling mold having the opening bag-shaped filling portion as the filling mold,
In addition to making it possible to manufacture filled molded products without score lines, it also aims to reduce the manufacturing cost of the filling mold itself and prevent damage to the filling mold, and at the same time greatly simplifies the manufacturing process and further to improve the viscosity of the filling material. It is possible to fill the inside of the elastic filling mold with a filling material so that air bubbles will not be generated regardless of it.
